Hi!
I had bios based RAID 1 on intel motherboard with 2 server.
If I don't use LVM Centos 7 cannot boot after install.
I cannot run this command, the output:
drbdadm create-md r0
open(/dev/sda4) failed: Device or resource busy
Exclusive open failed. Do it anyways?
[need to type 'yes' to confirm] no
Operation canceled.
Command 'drbdmeta 1 v08 /dev/sda4 internal create-md' terminated with
exit code 20

It's normal? I don't think so.

If I deleted the /dev/sda4 and created again with same size, it was
again drbd FS type, but I do nothing.
Any idea? What I do wrong?
Thanks,
